So, we would expect that the proto-lunar impactor was isotopically distinguishable from Earth, but the opposite was found: the Moon is made of the same raw material as Earth. While the ideas of a highly-titled Earth embedded in a hot, donut-shaped synestia may appear exotic, this is where the study of lunar formation has led us.

From year to year, the moon never seems to change. https://arxiv.org/abs/1705.07858  Matija Ćuk has been working with researchers Simon Lock and Sarah Stewart on a new theory. ©2020 SETI Institute. Unless we are taking about a box of donuts, which does contain a rough model of a synestia. Provides NASA HD Photo of the Day, Save photos to Google Drive directly.

In 2012, Sarah Stewart and I proposed that the solution to the question of lunar formation is tied to the loss of angular momentum at impact. Cosmochemists can tell if a new meteorite is from any of the known bodies using this isotopic signature. Ćuk et al. We will see how these ideas fare with time, and whether further surprises await us. Recently, the focus of simulations has been to explain the similarity in composition between Earth and the Moon.

The moon has no eroding atmosphere and no plate tectonics, so the violence of the early solar system is eternally etched onto the moon’s surface. The Solar System Simulator is a graphical engine which will produce simulated views of any body in the solar system from any point in space. Thanks to NASA’s Lunar Reconnaissance Orbiter, we now have a better look at some of the moon’s history.

This is in stark contrast to the situation fifteen years ag. In our 2012 paper, I showed that an orbital resonance between the Sun and the Moon in the distant past can remove spin from Earth-Moon system and transfer it to Earth's orbit around the Sun.

In this "classical giant impact" story a Mars-sized body hit Earth, at a relatively slow speed, along the plane of its orbit and somewhat off-center, and that this collision produced a disk of debris orbiting Earth, from which the Moon formed. Davis) on a new theory. However, no model has produced a stable Earth-Moon system from a single simulation.

The target has a density suitable for the lunar crust (~2700 kg/m 3).

Hi all, I put together a simulation of the collision thought to have formed the Moon. (2016) on early high-obliquity Earth. It is generally accepted by most planetary scientists that the Moon was formed in a giant collision between a growing Earth and another, smaller, proto-planet at the end of Earth's formation, about 4.5 billion years ago. Some 4.53 billion years ago, a Mars-sized impactor slammed into Earth, forming a young, molten moon.But was it a head-on collision or a glancing blow? And clicking and dragging from within the moon will display an arrow. After much further work, I realized that Earth can lose spin much more readily and robustly if its initial spin axis tilt was large, 70 degrees or more. The moon has no eroding atmosphere and no plate tectonics, so the violence of the early solar system is eternally etched onto the moon’s surface.
